**What is a Floor Joists Calculator**?

A floor joists calculator is a tool used to estimate the size and spacing of floor joists for a given floor area.

It helps in designing floors in buildings to ensure they meet safety and structural requirements.

**Why Use a Floor Joists Calculator**?

Using a floor joists calculator is essential in construction and engineering to determine the appropriate size and spacing of floor joists based on factors like span, wood type, live load, dead load, and deflection limit.

This ensures the structural integrity and safety of the floor.

## Floor Joists Calculator

A floor joists calculator is a tool used to estimate the size and spacing of floor joists for a given floor area. It requires input values for the span of the joists, the type of wood, the live load, dead load, and deflection limit, providing an estimate of the required size and spacing of the floor joists.

**How to Use a Floor Joists Calculator:**

- Input the span of the floor joists in feet.
- Select the type of wood from the dropdown list.
- Input the live load and dead load in pounds per square foot.
- Input the deflection limit in inches.
- Click the "Calculate" button to perform the calculation.
- The calculator provides the recommended size and spacing of the floor joists.

**Example Calculation:**

Suppose you have a joist span of 12 feet, using Douglas Fir-Larch wood, with a live load of 40 psf, dead load of 10 psf, and a deflection limit of 1/360.

Using the calculator, you would find that the recommended size of the floor joists is approximately 2.5 inches and the recommended spacing is 16 inches.
